MULTIPLEJAW WRENCH.

Application filed September 6, 1923.

This invention relates to multiple jaw wrenches, and particularly to awrench structure having a plurality of jaw portions which can beselectively brought into position for use to suit various requirements.

An object of my invention is to provide a tool of this cha 'acterconsisting of a rigid double end wrench having smaller single endwrenches attached on each side thereof and adapted to be swung out tothe position for use, in which latter adjustment the smaller orauxiliary wrenches clear the jaws of the main wrench.

A further object resides in so constructing and mounting the parts thatthe wrench has four different sets of aws and substantially twelvedifferent angles of disposition in which the various jaws can be used.

WVith the above and other objects in view which will be apparent tothose skilled in the art, my present invention includes certain novelfeatures of construction and combinations of parts which will behereinafter set forth.

In the drawing:

Figure 1 is a view in top plan of a wrench constructed in accordancewith my present invention.

.Fig. 2 is a view in edge elevation of the wrench.

Fig. 3 is a plan view of one end of the main wrench portion illustratingone setting and adjustment of one of the auxiliary wrench portions. v

Fig. 4 is a view similar to Fig. 3 showing a different adjustment.

The main wrench portion or body 1 is of the rigid double-end wrenchtype, with the jaws 2 and 3, preferably inclined on their central axes 2and 3, from the central axis of the body portion 1. The auxiliary wrenchmembers t and 5 are provided with smaller jaws 6 and 7. and have theirremaining ends pivoted on the sides of the body portion 1 by means ofpivot pins or rivets 8 and 9.

The auxiliary wrench portions 4 and 5 are so mounted on the body 1 thatthey can be swung to overlie the body portion on the upper and lowersides and in this position will entirely clear the jaws 2 and 3, thispivotal mounting, however, being at such points on the body portion 1that the auxiliary members 4: and 5 can be swung completely or partiallyaround from the position shown in Figs. 1 and 2, and in this adjustmentwill Serial No. 661,225.

extend to the positions for use, as shown in Figs. 8 and l.

It is preferable that the axes 6 and 7 extend angularly with respect tothe longitudinal axes of the auxiliary members a and 5, and stop lugs 10and 11 are provided on the upper and lower sides of the body portion 1and are positioned laterally with re spect to the central axis, so thatwhen the auxiliary wrench members are swung out to the positions foruse, they will be held in predetermined settings. As is shown in Figs. 3and 4, each auxiliary wrench member be adjusted to either of twosettings with res sect to the adjacent main jaw and the stop pin, andthe axial an le of any one of the jaws in any of the various adjustmentscan be reversed by turning the wrench over.

This wrench can be made of any suitable metal, and the jaw openingsmight be made of any polygonal form and might be set at other anglesthan those illustrated. It will also be appreciated that other changesand variations can be made in the form, construction and assemblage ofthe parts of my improved wrench without departing from the spirit andscope of my invention.

1 claim:

1. A multiple jaw wrench comprising a 8 rigid double end wrench portionforming a supporting body and having its jaws opening angularly from thelongitudinal axis of the body, a single end auxiliary wrench memberhaving its jaw opening angularly pivoted at its remaining end on thebody to be swung to a position to extend therefrom for use, and a pin onthe main wrench portion forming a stop to limit movement of the auxiliary wrench member when in a position for use, said auxiliary wrenchmember being adapted to be swung to a position on one side of the pin toextend substantially parallel with the supporting body and to a positionon the opposite side of the pin in which the auxiliary member isangularly disposed to extend from said supporting body.

2. A multiple jaw wrench comprising a rigid double end wrench portionforming a supporting body and having its jaws opening angularly from thelongitudinal axis of the body, a single end auxiliary wrench memberhaving its jaw opening angularly pivoted at its remaining end on oneside of the body adjacent one of the jaws thereof, a second single endauxiliary wrench member also having its jaw opening angularly pivbody,said auxiliary Wrench members being adapted to be swung to a position onone side of the pins to extend substantially parallel with thesupporting body and to a position on the opposite sides of the pins inwhich the auxiliary members are angularly disposed toextend from saidsupporting body.

In testimony whereof I hereunto aflix my signature.

JAMES M. LAFLIN.
